Compare traits between urban and non-urban species

Gape Width

ggplot(species_urban_response, aes(x = is_urban, y = beak_width)) + geom_boxplot()

wilcox.test(beak_width ~ is_urban, species_urban_response)

    Wilcoxon rank sum test with continuity correction

data:  beak_width by is_urban
W = 1525, p-value = 0.3893
alternative hypothesis: true location shift is not equal to 0

There is not a significant response for the gape width between urban species and non urban species.

HWI

ggplot(species_urban_response, aes(x = is_urban, y = hwi)) + geom_boxplot()

wilcox.test(hwi ~ is_urban, species_urban_response)

    Wilcoxon rank sum test with continuity correction

data:  hwi by is_urban
W = 1213, p-value = 0.01492
alternative hypothesis: true location shift is not equal to 0

There is a significant response between urban and non-urban species

Mass

ggplot(species_urban_response, aes(x = is_urban, y = mass)) + geom_boxplot()

wilcox.test(mass ~ is_urban, species_urban_response)

    Wilcoxon rank sum test with continuity correction

data:  mass by is_urban
W = 1825, p-value = 0.5168
alternative hypothesis: true location shift is not equal to 0

There is not a significant response between species.

Phylogeny

Phylogentic response to relative abundance?

tree = read.tree(filename(TAXONOMY_OUTPUT_DIR, 'phylogeny.tre'))
tree_pruned = ladderize(drop.tip(tree, setdiff(tree$tip.label, species_urban_response$ebird_species_name)))
ggtree(tree_pruned, layout="fan")

Scale for y is already present.
Adding another scale for y, which will replace the existing scale.

columbidae_response <- species_urban_response$mean_relative_abundance_proxy
names(columbidae_response) <- species_urban_response$ebird_species_name

Is the a phylogenetic signal for our relative abundance proxy

col_ut_phylo_signal <- phylosig(tree_pruned, columbidae_response, method="lambda", test=TRUE)
col_ut_phylo_signal

Phylogenetic signal lambda : 0.46832 
logL(lambda) : -576.839
